Motor and trans doing good.10,000 miles on new motor used 1/2 qt oil really good.Had to tow a scidstear for my Dan couldn't even tell it was even hooked to the truck.The Allison is great for towing.4 to 3 closed throttle down shifts still harsh.I put a MD tcm in mine everything was good except the 4 to 3 CTDS we have come to the conclusion it's the VB.
Going to set the fuel back up and maybe advance the timing a little.
